What Are Stretch Wrappers?
Stretch wrappers are machines that apply stretch film around palletized loads to secure products for transport and storage. The wrapper stretches plastic film (typically 80-gauge cast or blown polyethylene) around the load while rotating either the pallet or the film delivery system. This creates a tight, protective wrap that prevents load shifting, protects from dust and moisture, and improves warehouse safety by containing loose items.
Stretch wrapping is the final step in most packaging operations. After items are palletized, the stretch wrapper applies film in a consistent pattern with controlled film tension and overlap. Modern stretch wrappers use pre-stretch technology that stretches the film 200-300% before applying it to the load, reducing film costs while maintaining load containment. Automated systems can wrap 40-100+ loads per hour with minimal operator intervention.
Types of Stretch Wrapping Machines
Turntable Wrappers
Pallet rotates on turntable while film carriage moves vertically. Most common type. Suitable for stable loads up to 4,000 lbs. Semi-automatic or fully automatic.
Rotary Arm Wrappers
Rotating arm applies film around stationary pallet. For unstable, heavy, or light loads that cannot spin safely. Higher throughput capability.
Automatic In-Line Systems
Fully automated systems integrated with conveyors. Hands-free operation with cut-and-clamp film delivery. 40-100+ loads per hour.

- Max Load Height: 80-100 inches typical, customizable
- Film Width: 20 inches (hand roll), 30 inches (machine), custom widths available
- Pre-Stretch Ratio: 200-300% (reduces film consumption by 50-70%)
- Power Requirements: 110V single phase (semi-auto), 220V/440V three phase (automatic)
Applications and Integration
- End-of-Line Packaging: Final step before shipping, every distribution center and warehouse with outbound freight
- Manufacturing Facilities: Wrapping finished goods pallets before storage or shipment
- Cold Storage Operations: Special film formulations remain flexible in sub-zero temperatures
- Outdoor Storage: UV-resistant film protects loads stored outside
Stretch wrappers integrate with pallet handling conveyors that feed loads into the wrapper, packaging lines that palletize products, and industrial scales for weight capture before or after wrapping.
